HEAT DISTRIBUTOR FOR KITCHEN BOILERS.

Application fi'ecl May 28, 1927. Serial No. 134,931. 1

' This invention relates to a heat distributor adapted to he placed under receptacles containing food material, liquids and the like, and intervening between such receptacles and the source from which theheat is derived for cooking the contents thereof, the.

principal object being to prevent the burnmg, or scorching of the said contents.

A further object of the device is a means to graduate the air spaces under the said receptacles, from a high point near to the outer margin of the distributor, to a low point at the center thereof, thus providing for the passage of a greater degree of heat through the thin central portion, which heat gradually diminishes toward the outer parts. 1

These and other objects and features of the device will be found fully described in the following specification and illustrated in the accompanying drawings, in which:

liig. 1 shows a top View of the distributor in its simplest term. i

Fig. 2 shows a section thereof on the line 22 of Figure 1.

Fig. 3 shows another form of the invention, in which is provided a shut-oil gate in the channel groove. i

Fig. 1 shows a section on the line tl of Figure 3.'

Fig. 5 shows an enlarged fragmentary section on the line 5-5 of Figure 3.

Fig. (5 shows a form of the device having a triangular arrangen ient of the channel g1 'oo ves.

deterring now, to Figures 1 and 2 of the drawings, the device is here shown as a circular plate 10, which, while preferably of porcelain or aluminum, may be of any suitable material. This plate has a top surface 11 and a guard rim 12 around its outer edge. A groove, or channel 13, beginning at the surface of the plate at the point 14, gradually sinks to its lowest depth at the point of its termination in the center recess 15. A hole 16 is provided for hanging the plate on a hook, or the like when not in use.

It will now be seen that the greatest open area of the plate is at the central portion, and that this portion is also relatively thin as compared to the outer parts of the device. The heatis therefore delivered in its greatest volume under the center of the cooking container which is set over it; which causes, in the case of liquids, a circulation moving up from the center and, downward at the sides, thus more quickly and throughly heat- 7 Its general construction is the same as that,

first described. It is further provided, how ever, with a shutoff gate 20 which operates in the groove .21 and may he slid forward as illustrated, to close the channel 22 which is p the equivalent of that first shown at 13. A

recessed portion 23 permits of moving the gate by the end lip 24. The forward end of the gate ei'igages the seat recess 25. On reference to Figure 5, 1 slots 26 and 27 may be seen which serve to retain the gate in position. The curve of the recess 23 is here indicated by the dotted line so numbered. This gate may be used to shut oil the outer parts of the channel 22 to prevent any spilled over liquid from running down the incline of the said channel and collecting at the center of the distributor. When solids are in course of preparation, it may be left open.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is as follows:

1. In a heat distributor, a plate of suitable i'orm, and a channel in the said plate, which channel is so disposed, that winding about itself it passes from a point near to the outer margin of the said plate to a point of termination in a recess at the center thereof, the depth of the said channel varying gradually from its point of beginning, which is relatively high with respect to the said plate, to its point of termination which is low with respect thereto.

2. In an article of the class described, a flat plate of suitable form, an upward disposed guard rim around the outer edge of same, and a channel sunk into the said plate and having its outer end beginning at a point relatively high with respectto the body of the plate, and its depth gradually increased throughout its length to its point of termination in a recess at the center of the said plate.

3. In" an article oi ithe class described, a flat plate of! suitableform, aniupward disposed guard rim around the outer edge of same, and a channel of varying depth beginning ata point relatively high withrespect to the body of the said plate, and having its point of termination low with respect there, to, the said channel so disposed that its high end is located near to theiouter margin of the plate and its course from that point Winding within itself to the said point of termination,

and a central 1 recess opening: into the said point not above channel andit-sbottom at a' the-deepestiportion thereoii.

In aheat distributor, a llat plate, :1: marginal, upward disposed continuous rim thereonya central recess in the said: plate having a bottoxni area which is relatively tlllIhWfillli respect thereto, a channel! sunk into the body of: the said plate and so disposed that its pointoi beginning is near to the outer margiuthereot, and course from that point winding about itself toa point of juncture with the saidcentral recess, and its depth varying gradually from its point of beginning which ishi gh, to itspoint of termargin oiithc said plate to a point cl termination in a recess at the center thereof, the depthrof the said channel varyinggradually from its point of beginningwhich is rela tively high with respect to the said plate, to its point o't'lterininatiori, which is low with respect thereto, and 'located adjacent to the said channel, a slidable gate having; means to retain the same in; position, and hauung its top surfaceflnsh with the face of the said plate and its forward portion adaq'ited to be movedacrossthe said channel \and to cll'ec tively close it at this point, substantially as shown and tlCSCllbGtl herewith.
